Which is a factor that decreases rock strength along faults?
A) age
B) weight of glaciers
C) flowing water
D) sedimentation

Question

Quizplus · Accepted Answer

Flowing water can weaken rocks by increasing their susceptibility to weathering and erosion. It can also cause the rocks to undergo chemical reactions and mineral alteration, leading to their structural destabilization. This effect is particularly pronounced in fault zones where water can seep in and further weaken the rocks along the fault surface. Age (A) and sedimentation (D) may have an impact on rock strength, but these factors do not directly affect rock strength along faults. The weight of glaciers (B) may exert a compressive force on rocks, potentially increasing their strength, but this is not generally considered a factor that decreases rock strength along faults.
